The invention relates to a miniature simultaneous vision simulator instrument with various image-forming channels, each one of which projects, onto the retina of the same eye, a component image with a different degree of defocusing of the same observed object, such that the superposition of all of the component images forms a final simultaneous vision image on the retina of the eye. The instrument has at least one adjustable variable focus lens that, as the focus is changed, modifies the vergence of the light beam passing through said adjustable lens. Furthermore, one of the image-forming channels passes through the adjustable variable focus lens. The instrument can operate in the modality of optical channels that are physically differentiated in the modality of temporal channel multiplexing.

The present invention relates to systems and methods for providing a Push-Pull perceptual learning technique to a subject demonstrating sensory eye dominance (SED), amblyopia, poor stereopsis, and the like. More specifically, the weak eye of the subject is forced to become dominant, while visualization in the strong eye is suppressed over the course of a treatment regimen. Such systems and methods are shown herein to result in a perceptual learning and a reduction of interocular imbalance or SED, as well as an improvement in the visual characteristics typically associated with amblyopia, poor stereopsis and similar visual deficiencies.

Methods, systems, and storage media for projecting a viewer-specific 3D object perspectives from a single 3D display are disclosed. Implementations may: acquire face and eye region image data of a plurality of viewers within a field of view of at least one camera associated with a 3D-enabled digital display; analyze the eye region image data to determine at least one 3D eye position, at least one eye state, at least one gaze angle, and at least one point-of-regard for a viewer relative to at least one camera associated with the 3D-enabled digital display; and calculate a plurality of processed image projections for display by the single 3D display. The digital-processing of input image projection enables a separate optical input to the user's eyes, and by the use of visual-acuity pre-processing of the imagevia visual-field kernel, enables the treatment of eye abbreviations, including an Amblyopic-eye without the need for any additional eye-ware, or head-up-displays (HMD's).

Devices and methods are provided herein for aiding in the early diagnosis and remediation of conditions that range from unpleasant to disabling. Images are presented to viewers in an assembly that also eye-tracks their eyes during that process and executes software to identify visual signatures of conditions in the responses of the eyes. Also, responsive treatment for a thus-identified presentation of the condition can be effected in real time providing the patient with both a cause-and-effect perception of the presentation of the condition and means for correcting related ocular behaviors right when they occur.

A method for treating a weak viewer-eye includes the steps of receiving eye-strength data indicative of an eye-strength of the weak viewer-eye and causing a 3D display system to vary, in accordance with the eye-strength of the weak viewer-eye, display characteristics of a perspective that the 3D display system displays.

Devices and methods are provided herein for aiding in the diagnosis of and response to conditions ranging from unpleasant to disabling. Images are presented to viewers and eye-tracking of their eyes during that process along with software analysis non-subjectively identify and quantify complex visual signatures formerly hidden in the responses of the eyes. This allows caregivers, when presenting these images to people to be evaluated for a condition, to identify, again with eye-tracking and software analysis, those signatures indicative of a presence or an absence of the condition. An associated remediative response provides treatment applicable to a real-time environment.

A method of restoring binocular fusion and stereopsis in a patient exhibiting a functional scotoma includes determining that the patient has a treatable scotoma, presenting an object to be viewed by the patient, placing an eyewear apparatus with a right lens and a left lens in front of the patient's eyes, and treating the scotoma by alternately and sequentially occluding the right lens and the left lens at a frequency of 0.5-10 Hz when the patient's gaze is fixed on the object.

The present invention relates to an apparatus and method for providing virtual reality-based eye movement exercise and visual perception training, wherein a dichoptic presentation is provided in consideration of the deviation of a user's eyeball so as to prevent additional damage to stereoscopic vision due to suppression, and is provided by adjusting the degree of difficulty by changing the locations of visual stimuli on the basis of the level of deviation and training capability of the user, thus making it possible for the user to not only receive training suitable for the user's condition, but also simultaneously undergo visual perception training including eye exercise (movement) training and stereoscopic perception recognition.

A vision training device according to an embodiment of the present invention includes a deviation angle determining unit that determines a deviation angle and a deviation direction of a user, a strabismus correction value determining unit that determines at least one or more correction prism diopters and a correction direction based on the deviation angle and the deviation direction, a vision training unit that determines at least one of the correction prism diopters as a training range and guides movement of the user's eye in the deviation direction and the correction direction, and a refraction angle adjusting unit that changes a refraction angle of light entering the user's eye according to the deviation angle or at least one or more correction prism diopters included in the training range. Through vision training, weak eye muscles, which are the root cause of strabismus, can be strengthened.
